CHARLES A. ROLFE, OF ADRIAN, MICHIGAN, ASSIGNOR, BY MESNE AS- SIGNMENTS, TO ROLFE ELECTRIC CO., OF ROCHESTER, NEIV YORK, A

CORPORATION OF NEW YORK.

ELECTRIC HEATER.

SPECIFICATION forming part of Letters Patent No. 793,158, dated June 27, 1905.

Application filed November 14, 1903. Serial No. 181,172.

To all whom it may concern.-

Be it known that I, CHARLEs A. RoLFE, a citizen of the United States, residing at Adrian, in the county of Lenawee and State of Michigan, have invented a certain new and useful Improvement in Electric Heaters, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this IO specification.

My invention relates to electrical heating devices for heating articles by electrical energy.

The principal object of the invention is to 5 provide a simple and inexpensive device of this kind and one especially adapted for heating curling-irons.

In the accompanying drawings, Figure I is a view of an electrical heater embodying my present invention, together with a curlingiron used in connection therewith. Fig. 2 is atransverse section taken on line 2 2 of Fig. 1 with the curling-iron removed. Figs. 3 and 4 are respectively a longitudinal section 5 and an end view of a modified form of the device. Figs. 5, 6, 7, and 8 are similar views of still different modified forms. Fig. 9 is a longitudinal section, Fig. 10 an end view, and Fig. 11 a transverse section, of still an- 3 other modified form. Figs. 12 and 13 are respectively a side elevation and a cross-section of another modification.

Referring first to Figs. 1 and 2, A represents an incandescent lamp of usual or ordinary construction, having asubstantially cylindrical tubular bulb. Attached to this, as by means of a pair of bands 1 1, is a socket or sheath 3, which is adapted to receive the tongs of a curling-iron. In Fig. 1 such curl- 4 ing-iron Bis shown with its tongs inserted in the sheath 3. The sheath 3 is conveniently composed of sheet metal bent into the desired form, as shown in Figs. 1 and 2. It is desirably provided with a leaf-spring 4 for holding the tongs of the curling-iron .firmly in position and near the electric-light bulb. It will be seen that by this arrangement the curling-iron can have its tongs insertedin the sheath 3 and the current turned on in the lamp, with the result that the curling-iron will soon be 5 heated to a sufiicient heat for use. The sheaths for such an arrangement can be easily applied to the electric-light bulbs either temporarily or permanently. .In the former case the lamp could be used as ordinarily until it was desired 5 5 to heat the curling-iron, when the sheath or socket could be applied. In the latter case the lamp would be used, as a general thing, only for the purpose of heating the curlingiron, and so would be applied to a lamp-socket only when it was desired to heat the curlingiron. In such latter case the socket or sheath 3, with the clips 1 1, would be secured firmly to the lamp, as by cement or white lead or similar adhesive material, and,if desired,the lamp- 5 bulb can be painted or darkened, so as to prevent the giving of light and concentrate heat.

In the modification shown in Figs. 3 and I a graphite pencil 5 larger than a lamp filament is inclosed within an insulating tubular 7 sheath 6, the whole being arranged similar to an incandescent lamp. The sheath 6 is pro vided with a socket or sheath 7, desirably having a spring 8. In this arrangement a greater heating effect is secured because of the greater size of the carbon pencil 5 and also because of the proximity of the sheath 7 to said graphite.

In the arrangement shown in Figs. 5 and 6 an insulating-tube 9 is arranged within aninsulating-sheath 10. A fine wire is wound about the tube 9, which latter is arranged to serve as at sheath for the curling-iron tongs.

In the arrangement shown in Figs. 7 and 8 an electric-light bulb is specially constructed 5 with a flat longitudinal face 11, and a sheath or socket 12 is arranged against this fiat face, being held in position by clips or bands 13 13. The bulb is understood to contain a carbon filament, as usual. 9

In the device of Figs. 9, 10, and 11 is shown a speciallyconstructed electric-light bulb 14, having a centrally-formed socket 15, made of the wall or casing of the bulb, the filament 16 beilng confined in the annular space of the bu b.

In the arrangement shown in Figs. 12 and i 13 the lamp has a'p'ear-shaped bulb 17,-' and this is inclosed in a substantially continuous metallic sheath 18, which is lined with asbestos 19.

The socket 20 for the curling-iron is desirably made out of the metal forming the sheath 18, the lining of asbestos being terminated atithe sides of-the sheath, so asuto-allow the curlingand then the 1 current turned on, soithat *the curler is quickly heated. The foregoing are illustrative of various types of my invention,

although it will be understood that other forms may bedevised without departing from the spirit of the invention.

hat I' claim is- 1. An electric heater comprisingan-electric incandescent lam p, and 'a' deviceifor holding the I articletobe heated, said a device secured tovand supported 'by the lamp-so asto' cause the article-to be heated by the 'lamp filament,

substantially as described.

2. An electric heater, comprising an incandescentlamp, and a holder for an article to be heated, said holder being'secured to and-supported by the'lamp, whereby an article contained thereby will beheated by the lamp filament, substantially as described.

3. An electric heater comprising a holder for an article to be heated,-and securing means thereforconsi'sting of'means for encircling an incandescent-lamp bulb and securing the holder thereto.

4. An electric heater comprising a holder for an article to be heated -anda sheath'adapted to inclose'an incandescent electric lamp bulb and-secure the-holder thereto. n

5. The combination with an electric incandescent lamp, of a heating device comprising 'aholde'rfor the article to be heated, and means for encircling the lamp-bulb and tying the holder thereto.

6. A device o f'the class specified, comprisingacasing or'envelop, adapted for application to an electric-light globe, and provided with means for holding an article to be-h'eated, substantially 'asdescribed.-

:7. A device .of*the class -specified,comprising a'casingo'r envelop=adapted for application: to an incand'es'cent lamp bulbg and proivided witha socketfor "an: article to beheat- 'ed, substantially as described.

"8. The combination with @an electric-light globe, of awcasing F or envelop ad-apted to fit about the same and provided with' means for holding an article to be 1 heated, substantially as described.
